Non-fullerene acceptor ITIC can react with PEI (or PEIE), which destroys the original intramolecular charge transfer in ITIC.
The self-absorption effect is one of the main bottlenecks for laser-induced breakdown spectroscopy (LIBS) technique. In this Letter, LIBS assisted by laser-stimulated absorption (LSA-LIBS) proposed to solve problem. process LSA in reduction discussed and confirmed. serious phenomena spectral lines (K, Mn, Al) were not observed LSA-LIBS. full width at half-maximum (FWHM) K, Al was reduced about 58%, 25%, 52%, respectively. results demonstrate capability approach
Layered Ruddlesden–Popper (RP) perovskites have good moisture- and photostability. However, thermal stability of the RP is still a challenge. In this work, through joint theoretical experimental study, we report an intralayer A-site compositional engineering strategy to enhance perovskite solar cells. The triple-A-site-cation BA2(MA0.76FA0.19Cs0.05)3Pb4I13 (labeled as T-RP) cells retain 80% initial efficiency after being stressed at constant temperature 85 °C for over 1400 h in dark, which...
Carbon is a key element for steel properties but hard to be determined by laser-induced breakdown spectroscopy (LIBS). Utilizing the combination of carbon in analytes and nitrogen ambient gas generate carbon-nitrogen (CN) radicals, LIBS assisted with radical fluorescence (LIBS-LIRF) was proposed resonantly excite radicals instead atoms plasmas. The CN B2Σ-A2Π band were stimulated 421.60 nm laser wavelength emitted 388.34 fluorescence. results show that spectral intensity enhanced 2 orders...
Spatially selective excitation was proposed to improve efficiency in laser-induced breakdown spectroscopy combined with fluorescence (LIBS-LIF). Taking chromium (Cr) and nickel (Ni) elements steels as examples, it discovered that the optimal locations were center of plasmas for matrix iron (Fe) element but periphery Cr Ni elements. By focusing an laser at locations, not only also analytical accuracy sensitivity quantitative LIBS-LIF better than those plasma conventional LIBS-LIF. This study...
As a critical component in perovskite solar cells (PSCs), hole-transporting materials (HTMs) have been extensively explored. To develop efficient dopant-free HTMs for PSCs, decent hole mobility (>10–3 cm2 V–1 s–1) is critically essential, which is, however, seldom reported. In this work, we introduce two novel donor–acceptor (D–A) type conjugated polymers (PDTPC-1 and PDTPC-2) with narrow bandgap unit, i.e., fused dithienopicenocarbazole (DTPC), as the donor building block...
This paper describes the quantitative evaluation of self-absorption reduction minor elements in laser-induced breakdown spectroscopy assisted with laser-stimulated absorption.
Siloxane-terminated polymers with low surface energy were studied as dopant-free HTMs in PSCs. The siloxane-terminated side-chains assisted the dissolution, tuning mobility, passivating perovskite defects and enhancing hydrophobicity of polymer.
Plastics play an important role in manufacture and our daily life. In order to realize fast classifications of plastics products, this paper proposes a method using laser-induced breakdown spectroscopy (LIBS) combined with principal component analysis (PCA) K_nearest neighbor algorithm (kNN) achieve highly-accurate classification plastic products small amount data training. After dimensionality reduction by PCA, the higher reduction, average recognition accuracy samples, but rising trend...
Modifying SnO<sub>2</sub>with PEI/PEO to improve the efficiency and stability of non-fullerene organic solar cells.
The whole ecosystem is suffering from serious plastic pollution. Automatic and accurate classification an essential process in effective recycle. In this work, we proposed approach for plastics using a residual network based on laser-induced breakdown spectroscopy (LIBS). To increasing efficiency, the LIBS spectral data were compressed by peak searching algorithm continuous wavelet, then transformed to characteristic images training validation of network. Acrylonitrile butadiene styrene...
